Alan Riach said: "top ventilation is therefore important. Many beekeepers in
the West of Scotland (the wet side) put matchsticks under the 4 corners of
the top cover boards in winter to provide this top ventilation and to
prevent the water vapour recondensing on the inside of the cover board."

When I was keeping bees north of Indianapolis, Indiana, I put small blocks
of 3/4" wood between my inner covers and outer covers.  Only had bees for
about six years up there before I moved to south Texas, but never lost a
hive over the winter (between six and eight hives).  Mike
